An Active Directory compromise is rarely a linear execution; it is an intricate web of chained micro-flaws. For example, Active Directory Certificate Services (ADCS) is an undeniable Tier 0 asset, carrying the same blast radius and criticality as a domain controller. When organizations fail to enforce strict Tier 0 containment, catastrophic domain compromises can and do occur.

This technical masterclass dissects a complete enterprise domain takeover that weaponizes the implicit trust architecture of (ADCS), exposing a critical architectural vulnerability: the fatal intersection of an over-privileged CA manager and a certificate template that blindly trusts user-supplied identities. Using ADCS exploitation as a practical example, learn how the absence of Tier 0 hardening enables attackers to dismantle every defensive guardrail … and what you can do to stop them.
